I have a sim & security unlocked Sprint phone touch pro 2 that we use on the AT&T network, USA. It works well, and registers with AT&T, but then after a bit it gets dropped, and pops up asking if you want to register with the network again. My friend has the same thing, and we are using different ROMs, and have tried different radios, but we both have this same issue. Does anyone have any idea how to resolve this issue, maybe a registry edit or something?
thanks.
I'm also curious about this. I'm on Verizon and was given the phone to keep from my last employer and my new one uses AT&T. I haven't done enough digging yet but wanted to *bump* this thread as I'm looking to keep my CDMA VZN phone and use it on AT&T permanently and wanted to know if there are others who have done this already.
*Anyone had success with using their CDMA phone with AT&T/Tmobile without GSM disconnecting as the OP mentions?

wooties, I read somewhere where the verizon touch pro2 works for AT&T GSM in the us, but not sure where. Search xda and ppcgeeks. I have the Sprint touch pro 2.
I just answered this one in another thread, so here is a copy and paste...
With your AT&T SIM in you probably need to set to manual network instead of automatic so it stays connected to AT&T and doesn't try to flip back to CDMA - if you've already one this, then someone else will have to jump in, but the settings are:
All Settings > Personal > Phone > Network (tab) > Mode of Operation = GSM/UMTS Only
This should keep it from jumping back to Sprint and then back to AT&T where it asks you to register again...
Remember though, with a CDMA world phone, you will only get 2G coverage here with your data as the 3G radio is a different frequency.
Hopefully that does the trick - and if not, someone else jump in and save them quick!
Purchased an HTC M8 from a friend that seems like was flashed to T-mobile. I tried everything and various roms (revolution, viper, bonestock) and the stock vzw RUU to get the phone back to verizon. The APN file is still showing all t-mobile files in it.
Also if I go into settings>Network preference: It shows all european networks ie: vodafone UK ,Claro dom,JP DOCOMO, all GSM/UMTS.
I called verizon to verify the IMEI and sim and they both checked out to be verizon, so I know its a verizon phone. Has the VZW logo on the back also.
I cannot make calls or get any internet connection with it. Tried changing all of the network settings, replaced the sim card and so far no go. Can anyone point me in the right direction for some help.I have searching and tried various procedures for the past 2 days without any luck.
Strange thing is the 4G icon is there and when i try to connect to the internet the bars below it become active but I always get the same message: Cannot connect to the internet.
The phone is rooted, TWRP, S-off and CID 11111111 also.
Thanks for any help !

Check your IMEI number, settings>about>status http://swappa.com/esn use this site to see if its bad or not. If it is, the phone was probably reported stolen or the person who bought it didn't pay the monthly amount for the phone, so Verizon would have blacklisted it
I called verizon and first verified that is was indeed a verizon phone which it is and it is ok to be activated. I took it to the store an they tried a new sim card but it did not work. No phone calls or data
No matter what RUU or rom i tried flashing when I check the apns-conf.xml file in System>etc it always ends up having T-mobile settings in there.
I have it rooted, S-off, SuperCID11111111, and nothing has worked so far. Very frustrated as I have been working on it going on 3 days. But not all is lost. I have have learned a lot trying to get it fixed. I just might end up sending it in to HTCand have them fix it. Sure would suck to have a $400 paper weight
Thanks for the reply..
At boot time, Android determines the correct network configuration based on the MCC and MNC from the SIM card and automatically configure all network settings.
I have a verizon HTC One M8 (had my imei verified at a verizon store and esn was clean) with a new sim card and yet all of the files in my system>etc>apns-config.xml file are showing T-mobile.
Also in settings>Network Preference>all of the carriers are coming up vodafone, CLARO DOM, JP DOCOMO Swisscom and they are all GSM/UMTS.
Does anyone know why its not loading the proper files from my sims MCC and MNC ? This has been driving me crazy for the past 3 days trying to figure this out.
I flashed stock RUU and am s-off, unlocked, Super CID 11111111. Have no idea what is causing this.Any help or pointing me in the right direction would be GREATLY appreciated.
Well, Sent it in for repair. Told the Customer rep the phone was roooted, Rom'ed, CID'ed and that I never got to activate it.
So just waiting to see what happens and will post when I find out the verdict.
BTW, they could tell when I gave them the IMEI the day that the phone was rooted. Is that possible ? Sure came as a surprise to me. Gave the lady the IMEI # and after about 1 minute she came back on and told me the phone was rooted on May 1st. I have no idea if that is true because I have only had the phone for 1 week now.
Hello I have a Sprint HTC A9 that has been successful unlocked for domestic use, but I have voice with no data. I have S-Off, boot loader unlocked, running stock os. Has anyone else ran into this problem? Can someone please advise?
A friend mentioned that the Sprint variant might not have correct bands installed to be compat with other carriers. I'm wondering if replacing the radio firmware with the developer edition version would work, but I can't get around simlock to test.
HTC A9 Sprint Unlock success!!
Please share? I've been trying for days and made little progress.
There is a guy from Craigslist in my area that did it and he will not tell me, I asked. If there is any kind of way that I can back it up, screen shot it, or whatever. Someone please let me know. I don't have any personal data on it, because it has no data so I'm not using it yet. I don't care about sharing. Let me know and I'm more than happy to.

If it's an MSL code, he should have supplied that for you. I think MSL is unique to the IMEI/MEID/ESN of your device.
About your successful unlock, congrats! Your success let's me know it's do-able. I'm calling a local computer repair shop that offers unlocking services tomorrow. :fingerscrossed:
I've tried a half dozen ways to get this phone unlocked, but so far I've come up empty except for one scenario:
S-OFF
1. Change CID/MID to unlocked and flash unlocked RUU. Phone works fine, radio not functional.
2. Change CID/MID to sprint and flash sprint RUU. Phone will work with T-mobile SIM for one boot-up. As soon as phone is rebooted the SIM locks.
You can't just reflash the sprint RUU either. If you want to get another successful boot, you have to flash the unlocked RUU, then the sprint RUU and you'll get one boot. My only guess is something in the partitions is zero'd out by the unlocked RUU. I've also tried using the CM13 build immediately after the sprint RUU, and again I get one boot, but as soon as I reboot, CM13 shows sim not inserted.
Perhaps someone can make sense of this.

Wow.... you are a life saver Lussardi! Thank you very much!
My HTC A9 has delivered APN setting, which cannot be modified. However, I was able to create a new APN manually and use that one. After that, data started to work. So far, I see it was able to connect to 4G and also LTE. At one place with strong LTE signal, i tested the download speed, and it was 82mbps. I have never seen that kind of download speed on my iPhone.
Thanks,

// , Did you unlock an HTC One A9 [Sprint] for complete LTE on T-Mobile or on AT&T?
// , Let me make sure I understand this correctly.
Can I do the following:
1. Unlock a Sprint HTC One A9.
2. Buy a data-enabled T-Mobile SIM card or AT&T SIM card.
3. Enter APN & Data settings.
4. Use that same HTC One A9 with T-Mobile or AT&T, with no loss in performance?
If this is true, that surprises and pleases me.
I assume that one can unlock an AT&T HTC One A9 for use with T-Mobile with no loss in performance, as well?

My Sprint version of HTC A9 has been working on T-Mobile's network for almost a week now. I see no issues so far. Data connection is still good with connecting to LTE most of the time.

i am not sure if my experience is any different from others here. but, here's the detail of what i went through....
My Sprint variant of HTC A9 was purchased directly off htc.com back in 11/2015. Since the phone was paid in full, I believe the phone was not locked to begin with. I had been using it on Sprint for the past 10 months. Just recently i switched my plan to T-Mobile. With T-Mobile's sim, I see the phone picked up the sim card. Phone started to work (i can make/receive calls) but data would not work. I talked to a couple of HTC rep for support. Both of them told me it should work. From their understanding, A9 and the new HTC 10 should work on all US major carriers...especially mine is a CDMA phone. According to them, CDMA ones can work on GSM....but GSM would not work on CDMA network. Anyways, they were no help for me.
I started doing research on my own and found many people experiencing the same. Phone would work but data would not connect. It was not working until a member on this board, Lussardi, came to rescue. He suggested to manually put in APN. So, I started to check out the APN setting. I see with t-mobile's sim card in, the phone is using a delivered T-Mobile APN setting. I went ahead and created one myself named T-Mobile Manual. I put in APN: fast.t-mobile.com and MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc and left everything else default. After I selected to use this new APN, the phone started to pick up mobile data. Now, depending on the area that i am in, i can see it's using either 4G or LTE. At one place with strong LTE signal, i did a speed test. It was over 80mbps.
Anyways, that's all. Good luck everyone.
// , Thank you!
// , Thanks for the thorough response, and for not just giving up.
The large corporations generally don't care too much about usability for this sort of outlier customer experience.
Can you give any instructions on how you unlocked the sprint version of the HTC A9?
Thanks.
Hey just looking to see if anyone has any thoughts or any ways of helping me.
I have purchased the vzw "unlocked" version from the B+H sale.
Threw in my Rogers(Canada) sim and it connected to lte and I was able to phone/text...
WIthin the hour I updated software to android 11 and the phone no longer recognizes the Rogers sim. When I go to Sim and Network it just constantly cycles off and on.
I have swapped with 3 sims (Telus, Rogers, and the VZW that it came with) and they all do the same thing in the settings page of just turning off and on.
VZW support was no help.
Oneplus support was no help.
Am I returning this as my only option?
Thanks,
